WARNING: Replace vacuum pad if sealing edge has any nicks, cuts or abrasions.
• Wear, stiffness or glaze: See Friction Coefficient preceding. Replace any pad that exhibits
wear, stiffness or glaze (see REPLACEMENT PARTS LIST).
Pad Cleaning
Regularly clean the face of each vacuum pad to remove oil, dust and any other contaminates.
Acceptable cleaning agents include soapy water and other mild cleansers. Do
not use solvents,
petroleum-based products (including kerosene, gasoline and diesel fuel) or any harsh chemicals
for cleaning. Do
not use unauthorized rubber cleaners or conditioners, such as those intended
for cleaning tires or vinyl surfaces, because those products can leave a hazardous film on vacuum
pads which significantly reduces their lifting capacity (see Friction Coefficient preceding). The
use of any unauthorized cleaning agent is prohibited because it could damage the pad and/or
create a hazard to the operator or others.
WARNING: Never use solvents, gasoline or other harsh chemicals to clean
vacuum pad.
WARNING: Never use unauthorized rubber cleaners or conditioners to clean
vacuum pad.
To prevent liquid from contaminating the hand cup during cleaning, cover the suction hole in the
recess for the filter screen or make sure the pad faces downward. Use a clean sponge or lint-
free cloth to apply an authorized cleanser and wipe the pad face clean. A toothbrush (or similar
brush with bristles
that do not harm rubber) may be used to remove contaminates clinging to
sealing edges.
6
Wipe all residue from the pad face, and allow the pad to dry completely before
using the hand cup.
5
If the hand cup is equipped with a VPFS10T pad, the sealing edge is the replaceable sealing ring. When it is damaged, install a
new sealing ring insert. In such cases, see T
O
Replace Sealing Ring Insert in VPFS10T Vacuum Pads.
